Replace jquery FormData for file upload javascript

Replacing FormData

Recently there was the requirement to upload file using jquery but for some reasons i found out that the uploading thing is working in properly in Firefox, chrome and safari but not functioning in IE(Internet Explorer).After long search, i had to manage the upload with an iframes for IE,below is the function that did magic :) enjoy

      
function fileUpload(form, action_url, div_id) {
    // Create the iframe...
    var iframe = document.createElement("iframe");
    iframe.setAttribute("id", "upload_iframe");
    iframe.setAttribute("name", "upload_iframe");
    iframe.setAttribute("style", "border: none;display: none;");
 
 
    // Add to document...
    form.append(iframe);
    window.frames['upload_iframe'].name = "upload_iframe";
 
    iframeId = document.getElementById("upload_iframe");
 
    // Add event...
    var eventHandler = function () {
 
            if (iframeId.detachEvent) iframeId.detachEvent("onload", eventHandler);
            else iframeId.removeEventListener("load", eventHandler, false);

            // Message from server...
            if (iframeId.contentDocument) {
                content = iframeId.contentDocument.body.innerHTML;
            } else if (iframeId.contentWindow) {
                content = iframeId.contentWindow.document.body.innerHTML;
            } else if (iframeId.document) {
                content = iframeId.document.body.innerHTML;
            }
 
            //getting the response from server 
           content = content.replace("","").replace("","");
          alert(content);
        }
 
    if (iframeId.addEventListener) iframeId.addEventListener("load",eventHandler,true);
    if (iframeId.attachEvent) iframeId.attachEvent("onload", eventHandler);
 
    // Set properties of form...
    form.attr("target", "upload_iframe");
    form.attr("action", action_url);
    form.attr("method", "post");
    form.attr("enctype", "multipart/form-data");
    form.attr("encoding", "multipart/form-data");
 
    
    form.submit();// Submit the form...
 
}
